Bryan Boreham 56491b35f1 Go 1.13 needs different static linking flags 
We don't need to pre-build the Go standard library or use -i flag
either - Go sorts that all out for us now.

Bryan Boreham 79e032c984 Reduce time test script waits for IPs to be reclaimed 
Now we have a callback when a node is removed, there should be no
reason to wait 90 seconds.

The reclaim does wait up to 5 seconds before starting, so allowing 10
seconds in the script should be sufficient.

Bryan Boreham 821b787774 Move printing of node addresses after reclaim loop 
Otherwise we see all the node addresses in the middle of the log.

Bryan Boreham f5c2f51964 Use a different seed for random numbers each run 
Without this, each run gets the same random numbers so all nodes are
racing to remove the deleted node.

Bryan Boreham d1ed6c5747 Exclude myself when building a list of peers that may need deleted 
We already avoid actually doing the delete, but adding this check
stops the program logging that it was thinking about it.

Bryan Boreham 44f91950cb Improve logging of ring merge 
Turn some Sprint() calls into `%v` in the outer format string.
Remove one debug log line on duplicate token, since that info is already logged.

Add an Info log line when we accept another peer's token, since that
should be a rare event, and it's important if we've made a mistake.

Bryan Boreham d2f0287fa3 Handle range wrap-around when checking for allocations 
Ring wraps around at zero but Space doesn't know about this, so we
have to normalise ranges coming out of Ring.  In turn we may need to
split one range into two, across the end of the Ring.

 2019-10-02 14:57:27 +01:00
Bryan Boreham ee47f0c3ee Use buffered chan to avoid losing docker events 
Docker imposes a limit that events have to be retrieved within 100ms
or they are dropped on the sending side. Adding buffer space within
the Weave Net process allows those events to be collected from Docker
more quickly.

1024 is an arbitrary number, much higher than we expect to need.

christian-2 6afedb881c mark pods weave-net with priorityClassName: system-node-critical 
* fixes #3691
* `weave-daemonset-k8s-1.11.yaml` is `weave-daemonset-k8s-1.9.yaml` plus `priorityClassName: system-node-critical`
* notice that a Kubernetes cluster created with `kubeadm` has its `kube-proxy`s marked as `system-node-critical` (and several other pods, such as `kube-apiserver` marked as `system-cluster-critical`)
